The pivot 32 is in the form of a stud similar to h and as a thumb screw w, similar to y'. The

shown in the drawings, or by securing both studs at the ends of? the legs to the base-with the p11 tai point 5 at the top. in either case the angle member constitutes with the base a hevei, the angie oif which may be varied as udy .escriued, iThus the device constitutes adjustable square or bevel, as de sired, suited to the great variety of uses to which such instruments are put in carpentering and building.

I claim:

A carpenters instrument comprising a straight base consisting of a pair of bars spaced apart to provide a slot therebetween, said slot being open and unobstructed from end to end, and said bars being secured to gether by a series of yokes, an angle member mounted on said bars and adJuStable length Wise thereof, and clamping means exten in" through said slot adapted to secure sai angle member in adjusted position.
